1. In America, it is literally incorrect to capitalize articles, conjunctions, and prepositions in titles.
2. I was not aware that it changed around the world, hence why my post said it was incorrect.
3. Kindly stop trying to belittle the US every chance you get. We have our faults, but calling our grammar inferior is beyond absurd.
American English is demonstrably inferior and incorrect, so I will belittle it every chance I get.
Or I'm just a pedantic arsehole, one of the two.
